MOSCOW, May 6 (Reuters) - Rosneft's export-oriented Tuapse oil refinery, one of largest in Russia's south, has resumed oil processing, two industry sources told Reuters on Tuesday, after the plant was damaged by fire in January.

They said the refinery completed repair work at the primary oil refining unit CDU-12, with capacity of around 250,000 barrels per day (bpd) at the end of April.

They said oil processing volumes at Tuapse amounted to 20,000 metric toms on May 1. (Reporting by Reuters Editing by Mark Potter)
